GrimmSpeed Top Mount Intercooler Silicone Coupler Kit - 2004-21 Subaru STI, 2002-07 Subaru WRX

Excellent product

Excellent hoses! Need to trim approximately 3/4 inch from both ends to fit stock 2021 STi intercooler, but the company mentions trimming may be required for proper fitment. The first time I ordered these, I got the clamps with the 8mm bolt for adjustment. The clamps I received with this order were smaller, and I had to use a screwdriver to tighten. Not a fan of the smaller clamp fasteners.

I had to cut the 90 degree coupler I guess if you buy the Grimmspeed tmic you don’t have to. But overall the product is good
